hubot 初探

hubot 是什么？

Hubot is your friendly robot sidekick. Install him in your company to dramatically improve employee efficiency.
更多介绍，请到官网，这里就不做翻译了 https://hubot.github.com/

如何搭建hubot服务？

1. 安装实例化 hubot 工厂。

依赖 npm ，这里默认你已经安装好  npm环境。这步相当于修建了一个制造机器人的工厂。

npm install -g yo generator-hubot

2. 配置命令 

把安装完生成的 yo 通过软连接方式放进已经配置好的环境变量目录，方便后续可以直接调动 yo 命令。如果所运行环境没有添加 /usr/local/bin/ 到环境变量，可以把 yo 放入 /usr/bin 目录

ln -s /usr/local/node/bin/yo /usr/local/bin/yo 
ln -s /usr/local/node/bin/yo-complete /usr/local/bin/yo-complete

3. 实例化一个机器人。

这个机器工厂可以生产适配各个环境运行的机器人（Adapter），目前有这么几种，官方提供：Shell、Campfire，其他流行的几种分别为：Gitter、HipChat、IRC、Rocket.Chat、Slack、XMPP。还有更多，这里附上 github 地址 https://github.com/search?q=topic%3Ahubot-adapter&type=Repositories 。
下面用默认Adapter（campfire ）做一些展示，当然在国内还是wechat 更流行，上面的搜索结果我已经看到了适配 wechat 的 Adapter 了，抽时间再试试效果。接下来的步骤建议使用非root权限操作，否则会提示config目录/文件权限问题，我这里切换为普通账户，错误信息类似

/data/nodejs/lib/node_modules/yo/node_modules/mkdirp/index.js:90
                    throw err0;
                    ^

Error: EACCES: permission denied, mkdir '/root/.config'
    at Error (native)

    at Module._compile (module.js:570:32)
    at Object.Module._extensions..js (module.js:579:10)

3.1 新建目录，初始化 hubot （campfire Adapter）

mkdir myhubot3 
cd myhubot3/ 
yo hubot

1. May we anonymously report usage statistics to improve the tool over time? 
2. Owner 
3. Bot name 
4. Description 
5. Bot adapter

3.2 启动 hubot 

bin/hubot

有可能会有些报错信息，不过正常情况是可以直接回车略过，这里罗列一些简单的预制命令：

myhubot3> myhubot3 ping
myhubot3> PONG

myhubot3> myhubot3 animate me
myhubot3> Google Image Search API is not longer available. Please [setup up Custom Search Engine API](https://github.com/hubot-scripts/hubot-google-images#cse-setup-details).

myhubot3> myhubot3 help
myhubot3> Shell: myhubot3 adapter - Reply with the adapter
myhubot3 animate me <query> - The same thing as `image me`, except adds a few parameters to try to return an animated GIF instead.
myhubot3 echo <text> - Reply back with <text>
myhubot3 help - Displays all of the help commands that Hubot knows about.
myhubot3 help <query> - Displays all help commands that match <query>.
myhubot3 image me <query> - The Original. Queries Google Images for <query> and returns a random top result.
myhubot3 map me <query> - Returns a map view of the area returned by `query`.
myhubot3 mustache me <url|query> - Adds a mustache to the specified URL or query result.
myhubot3 ping - Reply with pong
myhubot3 pug bomb N - get N pugs
myhubot3 pug me - Receive a pug
myhubot3 shellcmd - list (bash)shell commands
myhubot3 shellcmd <foo> - performs bashshell command
myhubot3 the rules - Make sure hubot still knows the rules.
myhubot3 time - Reply with current time
myhubot3 translate me <phrase> - Searches for a translation for the <phrase> and then prints that bad boy out.
myhubot3 translate me from <source> into <target> <phrase> - Translates <phrase> from <source> into <target>. Both <source> and <target> are optional
ship it - Display a motivation squirrel

4. 让 hubot 执行 shell 、PHP 脚本

可以使用nodejs 来开发机器人执行的口令，也可以借助已经实现的 shellcmd 扩展来自定义一些口令

npm install hubot-script-shellcmd
cp -R node_modules/hubot-script-shellcmd/bash ./

修改一下external-scripts.json，添加上以下模块：hubot-script-shellcmd。如果到此为止，你操作的步骤和我基本一样的话，你的external-scripts.json应该长的像这个样子：

[
  "hubot-diagnostics",
  "hubot-help",
  "hubot-google-images",
  "hubot-google-translate",
  "hubot-pugme",
  "hubot-maps",
  "hubot-rules",
  "hubot-shipit",
  "hubot-script-shellcmd"
]

#!/bin/bash
top -b -n2 -p 1 | fgrep "Cpu(s)" | tail -1 | awk -F'id,' -v prefix="$prefix" '{ split($1, vs, ","); v=vs[length(vs)]; sub("%", "", v); printf "%s%.1f%%\n", prefix, 100 - v }'

exit 0

#!/usr/local/bin/php
<?php
echo "Hello..";

$input = array(

 '玫瑰花园自助烤肉（青年路店）',
 '又见成都',
 'Miss火新派重庆火锅',
 '大董',
 '京味缘烤鸭',
 '妈妈的味道',
 '七号鲜',
 '花牛餐馆',
 '金手勺',
 '达美B1食堂',
 '大鸭梨(石佛营店)',

);

$rand_keys = array_rand($input, 1);
echo $input[$rand_keys];

?>

myhubot3> myhubot3 shellcmd
myhubot3> spawn!
available commands:
  cpu
  eat
  helloworld
  update


myhubot3> myhubot3 shellcmd cpu
myhubot3> spawn!
5.0%

myhubot3> myhubot3 shellcmd eat
myhubot3> spawn!
Hello..达美B1食堂
